NGS Benchmark Database?

[GISed2007]

Hi I'm new here and Im doing a project for my GIS course at school and one of my projects is to obtain all benchmarks around the area where we are doing the project of.

 

My problem is I can't find any downloadable data of Benchmarks for my area or anywhere, does NGS have them on download somehwere or are they on file somehwere else?

 

If you guys knows anything about this, I t will be much aprreciated! thank you!

Hi - I'm from PA as well - if you're looking for NGS info go here:http://www.ngs.noaa.gov/cgi-bin/datasheet.prl -...the easiest way to start might be to look them up by county or radial search. (this is where the GC info originally came from, although GC's is a few years out of date)

You may also find some helpful info in THIS THREAD, particularly in THIS POST about County downloads.

 

Hope this helps!

Although they most likely won't be NGS disks, you might also consider contacting your county, state and DOT survey offices to see if they have disks in your area.

I'd start with the NGS on-line data base as Ernmark suggested. However, there are many other disks that aren't list in their database. You might want to check out the quadrangles for your area. There will be an X on the map with the letters BM indicating that a benchmark should be at that location. I have provided links to a few sites where you can get quadrangles for PA.

Also try checking http://www.Waymarking.com and do a search in the Recovered US Benchmarks category. Good luck with your search!

Does anyone know how to get a huge list of benchmark datasheets from the NGS, larger than 1 degree by 1 degree. I would like to retrieve them from geocaching.com so I could see the logs. Thanks.

The rectangular search function for NGS datasheets (http://www.ngs.noaa.gov/cgi-bin/datasheet....Type=DATASHEETS) allows an arbitrailarily large area BUT it will only return a maximum of 3000 stations. I tried a 2 x 2 degree area but I hit that limit. If you have a sparsely populated area you might get it to work.

 

Soo ..

 

Go with the county downloads and a program like GSAK. That's probably the most useful combination you will get.

 

I don't know how to retrieve groups of logs from Geocaching.som so someone else will have to answer that.

 

I did write a macro to display the Geocaching.com log for a station that works from within GSAK, if that would be of any use. But first decide if GSAK is something you want to work with - I like it a lot.
